Bru na Boinne, Newgrange, Meath, Ireland

Notes: "Newgrange was built in a time when there was only stone, not metal, used as an everyday material for tools and weapons. In 1993, Newgrange and its sister sitesKnowth and Dowth were designated a World Heritage Site by UNESCO because of their outstanding cultural legacy.

The Tuatha Dé Danann, who ruled Ireland in ancient mythology, were said to have erected Newgrange as a burial place for their chief, Dagda Mór, and his three sons. Newgrange was said to have been the place where the great mythical hero Cúchulainn was conceived by his mother Dechtine. His spiritual father, Lugh, visited Dechtine in a dream while she stayed at the Brugh."
